BACKGROUND It is important to include large sample sizes and different factors that influence the six-minute walking distance (6MWD) in order to propose reference equations for the six-minute walking test (6 MWT). OBJECTIVE To evaluate the influence of anthropometric, demographic, and physiologic variables on the 6 MWD of healthy subjects from different(More)
BACKGROUND Different types of nebulizers and interfaces are used for the treatment of adults and children with pulmonary diseases. The purpose of this study was to determine the efficiency of a mesh nebulizer (MN) with a proprietary adapter and a jet nebulizer (JN) under different configurations in adult and pediatric models of spontaneous breathing. We(More)
Excess body fat, particularly in the abdominal region, is responsible for respiratory system alterations. To study if and how both lung function and thoraco-abdominal volume variations during quiet breathing are altered in obese women and to determine if different obesity patterns in women have an influence on lung and chest wall function, 30 obese women(More)
OBJECTIVES This cross-sectional study was designed to examine the effects of the Valsalva Maneuver (VM) and its duration on the acid- base equilibrium of the neonate and its maternal repercussions during the expulsive stage of labor, after standard breathing and pushing instructions were given. METHODS A convenience sample of women with low risk pregnancy(More)
The intracellular redox state of alveolar cells is a determining factor for tolerance to oxidative and pro-inflammatory stresses. This study investigated the effects of intratracheal co-administration of antioxidants encapsulated in liposomes on the lungs of rats subjected to sepsis. For this, male rats subjected to sepsis induced by lipopolysaccharide from(More)
In areas with low house dust mite (HDM) allergen exposure, both mite sensitization and asthma prevalence are low. In most other areas, HDM allergen exposure is higher than the threshold for sensitization. In this setting, is HDM allergen exposure a factor which is causally related to the development of asthma in HDM-sensitive individuals? To answer this(More)
OBJECTIVE To analyze in obese women the acute effects of the breath stacking technique on thoraco-abdominal expansion. DESIGN AND METHODS Nineteen obese women (BMI ≥ 30 kg/m(2)) were evaluated by anthropometry, spirometry and maximal respiratory muscle pressures and successively analyzed by Opto-Electronic Plethysmography and a Wright respirometer during(More)
Objective: To determine the cut-off points for FEV1, FEV0.75, FEV0.5, and FEF25-75% bronchodilator responses in healthy preschool children and to generate reference values for FEV0.75. Methods: This was a cross-sectional community-based study involving children 3-5 years of age. Healthy preschool children were selected by a standardized questionnaire.(More)
